Hi all,
how do I trigger another pass?
Using md5 and io I want to save data to a helper file and reuse it in a
second pass (like e.g. mtx-context.lua) or update the file if
appropriate. But I couldn't quite figure out how to request another pass
>from the lua end.
there's
jobfiles.run(
"filename-to-be-checked",
"command-to-be-executed-if-changed"
)
Good evening, Hans!
Let me clarify my intention a bit: jobfiles.run calls "context" on the
argument list, but that is not what I need.
My problem is that I generate stuff during the tex run and want to
collect it in a table that is saved to a file at the end of the run.
This data is hashed at the beginning of the document and if the hash
does not match the end-run hash _or_ the file doesn't exist in the first
place, then I'd like to run another independent pass.
(I guess I could use jobfiles.run to process \jobname at the very end of
the document but would have to handle recursion somehow.)
so, as you save your data in a file, just after saving the table, hash
that file:
\starttext
test
\startluacode
jobvariables.tobesaved.MyPersonalChecksum = file.checksum("MyName")
or "no checksum"
\stopluacode
\stoptext
the context runner will take care of extra runs then.
(I'll think about a more robust user space for such status variables but
as long as you use UpperCased names you quite safe.)
